CHIMNEY=FLUE BRUSH.

SPECIFICATION forming part of Letters Patent No. 246,757, dated September 6, 1881. Application filed May 25, 1881. (No model.)

To all whom it may concern Be it known that 1, DAVID U. GREENWAY, of Abingdon,in the county of Washington and State of Virginia, have invented an Improved GhimneyFlue Brush, of which the following is a specification.

The object of my inven tion is the production of a brush by which chimney and other flues may be conveniently and thoroughly swept, and one which is adapted to flues of difl'erent sizes.

In the accompanying drawings, Figure 1 is a cross-section of my invention,taken on the line m w of Fig. 2; and Fig. 2 is an elevation, partly in section.

Similar letters of reference indicate correspondin g parts.

The block A is preferably of hard wood, and should be of such size as to easily pass through small chimney-flues,and is bored through with any desired number of holes a, which holes are preferably arranged spirally around the block. In the holes a are secured the metal casings or tubes 0 c, which may be of greater length than the diameter of the block, and are so placed in the holes through the block that the open ends thereof are flush with the periphery of the block. Within the tubes are placed the spiral springs d d, and upon these springs the shanks of the brushes D D rest, and the brushes are held in place in the tubes by the screws or pins 0, which pass through the slots 6 in the tubes and into the shanks of the brushes, as shown in Fig. 1'.

In the upper end of the block is secured, by means of the key I), the staple B, to which a rope may be attached for lowering and raising the brush through the flue; and to the lower end of the block is attached, by the rope or chain f, the weight E, which serves to cause the brush to pass down large and mediumsized fines of its own weight.

In case the weight is not sufficient to cause the brush to descend the flue, it will have to be drawn down by a rope, and for this purpose I provide the bottom of the weight with the staple 1;, into which the ropeJ may be attached when necessary.

In use the brushes are to be forced in upon the springs in the casing to such an extent that the device will enter the top of the flue.

The springs, being thus compressed, cause thebrushes to press against all sides and all parts of the chimney with a considerable force, and thus, in being drawn up and down the flue, accomplish the sweeping in a thorough manner.

It will be understood that the springs may be compressed to such an extentthat the brush is adapted to sweep all sizes of chimneys, small, intermediate, and large.

. Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- Thechimney-cleaning brush consisting ofthe wooden block A, diametrically bored through with numerous holes, spirally arranged, in combination with the slotted casingsc, secured in each of said holes, the spring d, and the brushes, as shown and described.
